Filed: 1995-03-30
Abstract: PURPOSE: To provide a power supply apparatus which reduces the pulsation of an output voltage and attenuates the harmonics of an input current and to provide a discharge-lamp lighting apparatus and a lighting fixture. CONSTITUTION: A power supply apparatus is provided with a rectifier device 4 which rectifies the output voltage of an AC power supply 1, with a first switching device 5 and a second switching device 6 installed in series at output terminals of the rectifier device and which are turned on and off alternately, with a series circuit, by a first capacitor 8 and an inductor 7, which is installed across the switching device on one side and which performs a smoothing action with reference to the output frequency of the rectifier device and with a second capacitor 11 which forms a resonance circuit in coorporation with the inductor according to the ON-OFF operation of the switching devices as one pair and whose capacitance is smaller than that of the first capacitor 8.  Consequently, by the action of a resonance voltage by the inductor and the second capacitor, an input current can be made to flow from the rectifier device over nearly the whole period of a rectified non-smoothed DC voltage, and the waveform of the input current is made close to sine waves so as to achieve a low distortion.

Title: Manufacture of crystal oscillator
Inventor: UETAKE HIROAKI
IPC: H03H3/02
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To almost eliminate the recontamination of an oscillator owing to the re-adhesion of pollutants by applying high frequency bias to the electrodes of the crystal oscillators, evaporating and removing the unnecessary part of an electrode pattern. SOLUTION: The crystal oscillators 5 where the formation of the electrode pattern terminals are arranged, in a chamber 1 and the inside of the chamber 1 is exhausted by a vacuum pump 4.

Thus, the pollutants adhered to the surfaces of the crystal oscillators 5 are removed by plasma generated in a processing in the device. Thus, bias current flows to the pollutants adhered on the surfaces of the crystal oscillators being insulating materials and therefore pollutants can be evaporated by generated heat by current. Then, the surface of the electrode is prevented from being damaged.

Title: Printer
Inventor: SUZUKI KUNIAKI
IPC: B41J25/304
Filed: 1988-03-30
Abstract: PURPOSE:To make possible color printing without printing quality deterioration caused by mixed color without reduction of throughput by providing a mechanism to adjust a gap between the tip of a printing head and a platen in opposite position to the printing head. CONSTITUTION:Color printing is performed by allowing a color zone corresponding to a designated printing color to be opposed to a printing head 11 by rotation of a color ribbon cassette 20. However, if a printing color is designated, CPU 41 reads the movement value of the color ribbon cassette 20 from a memory 43 with a carriage 12 set to a stand-still when the color ribbon cassette 20 is rotated, and drives a gap motor 29 based on said movement value. After this, an eccentric shaft 28 rotates through gears 30, 31 by driving of the gap motor 29, and the carriage 12 moves in a direction away from a platen 15 by a value equivalent to the number of steps. Consequently, a color ink ribbon stored in the color ribbon cassette 20 is not caught by the tip of the printing head 11 and color printing without print quality deterioration caused by mixed color is achieved by allowing the color ink ribbon corresponding to a printing color to be opposed to the printing head 11.

Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make uniform illumination distribution of illumination light and reduce the attenuation of light intensity for high output and high efficiency, by employing a light source that produces plasma discharge with torus-shaped intensity distribution in a light emitting tube, and taking out light with the assumption of a central axis of the plasma discharge of the torus-shaped light intensity of the light source being used as an optical axis. SOLUTION: When an AC current is applied from an oscillator 14 to a coil of a light source 1, a magnetic field is formed for the light emitting tube 11 over the entire periphery in the direction of winding of the coil, and electric discharge is produced on discharge gas in the light emitting tube 11 such that the discharge wounds around the magnetic field. Thereupon, plasma discharge of torus-shaped intensity distribution is produced in the light emitting tube 11 along the direction of winding of the coil. A diameter of a light emission cross section of the plasma discharge is about 8mm. Light is derived through optical means 2 using as an optical axis the central axis of the plasma distribution of the torus-shaped intensity distribution of the light source 1. A semiconductor wafer material 22 is irradiated with the light.  Hereby, illumination distribution of the illumination light is made uniform, and attenuation of the light intensity is reduced for high output power and high efficiency.

Title: Track counting circuit of optical disk reproducing device
Inventor: HORINO MAMORU
IPC: G11B7/085
Filed: 1992-02-26
Abstract: PURPOSE:To prevent a duplicate count caused by moving backward of a repro ducing spot by using an up/down counter of a small number of digits, in the case of counting the number of pieces by which the reproducing spot crosses a track, at the time of feed of an optical pickup. CONSTITUTION:A track crossing detecting means 12 outputs a pulse signal, whenever a reproducing spot crosses a track at the time of feed. A track crossing direction detecting means 14 detects whether the feed direction and the moving direction of the reproducing spot coincide with each other or are reverse to each other. An up/down counter 18 is held at a prescribed value at the time of non-moving backward, subjected to down-count, whenever the spot crosses the track at the time of moving backward, subjected to up-count, when moving- backward is obviated, and stopped, when the counter returns to the prescribed value. A unidirectional counter 16 executes a count at every crossing of the track, when the counter 18 is held at the prescribed value, and stops the count when the counter 18 is outside of the prescribed value and is executing a count operation. From the unidirectional counter 16, a track count value is obtained.

Title: Rectangular battery and its manufacture
Inventor: YAMAMOTO KEISUKE
IPC: H01M10/05
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a rectangular battery with a high capacity and its manufacture. SOLUTION: A battery has a generating element formed with two windings, for which a multiplex sheet A with at least two long sheets laminated is wound in the same direction or in mutually opposite directions with both longitudinal ends as winding start ends in such a manner that winding internal stress arising in winding is left. In this way the angular battery is easily formed. Still, an initial facing space between a positive electrode collector and a negative electrode collector is kept for a long time because the winding internal stress is left in the generating element, so that the battery can show stable capability and a long life.
